I faced with problem while fetching query results, my code:

$result = $query->execute();
$array1 = $result->fetchAllKeyed(1, 0);
$array2 = $result->fetchAllKeyed(2, 0);

But the $array2 is empty, so fetchAllKeyed cut all values from $result.

I'm already tried to use the following:

$query2 = clone $query;
$result = $query->execute();
$result2 = $query2->execute();
$array1 = $result->fetchAllKeyed(1, 0);
$array2 = $result2->fetchAllKeyed(2, 0);

It's works, but I don't want do two queries instead of one.

So, how can I do two (or more) different "fetch" from one result?

  • Did try duplicating the $result directly instead of recreating the query? $result2 = $result and then fetching the keys? May 30, 2015 at 9:55
  • Doesn't works too. If I use $result2 = $result; - I get empty fetch result. If I use $result2 = clone $result; - the same.

  • Hmm, then I guess you'll have to use fetchAssoc() wich gets you an array of objects and then use a foreach loop to generate the 2 sub arrays. Seems like the only solution. May 30, 2015 at 13:51

Since fetchAllKeyed() internally uses foreach loop to sort the data, the answer given by Suranga Panagamuwa Gamage to use fetchAssoc() and then a loop seems the most efficient way.
